Resumo(s)
Phosphogypsum (PG) is classified as a naturally occurring radioactive material (NORM) and contains elevated levels of natural radionuclides. This study employed alpha-particle and gamma-ray spectrometry to determine their activity concentrations in PG samples from selected Polish sites. Elemental composition was analysed using energy-dispersive X-ray fluorescence (ED-XRF) to give information on PG chemical characterization. Radiological hazard indices, including internal and external hazards and the activity concentration index, were calculated. The results show the potential of PG reuse in construction, demonstrated by its radiological profile, which meets recommended safety limits.
